Vaccinium membranaceum

Vaccinium membranaceum is an erect shrub growing up to 1.5 metres (4.9 ft) in maximum height. The new twigs are yellow-green and somewhat angled. The deciduous leaves are alternately arranged. The very thin to membranous, oval leaf blades are up to 5 centimeters (2 inches) long. The edges are serrated, with each tiny tooth tipped with a glandular hair. Solitary flowers occur in the leaf axils. Each is around 6 millimeters (1/4 inch) long, urn-shaped to cylindrical, and pale pink to waxy bronze in color.They are pollinated by bees. The mature fruit ranges from red through bluish-purple to a dark, almost black berry about a centimeter wide. Each fruit contains an average of 47 tiny seeds.
ReproductionThe plant rarely reproduces via seed, rather, it usually spreads by cloning itself from its rhizome or shoots. The seeds do germinate if dispersed by animals, however, as evidenced by populations of the plant growing on the recovering section of Mount St. Helens. Other than the study by Yang et al. (2008) reports of V. membranaceum sprouting from seed are quite rare with other scientists who have studied this species reporting only 6 seedlings observed during 18 years in the field.
